The invention discloses an absorption type refrigeration device adopting the technology of membrane distillation, which comprises a lean solution reservoir, a heat collector, a solution heater, a condenser, a throttle valve, an evaporator, an absorber, a membrane distillation generator and a heat exchanger for membrane distillation solution. The absorption refrigeration device is characterized in that: the hot water from the heat collector heats up the absorbent in the solution heater, and then delivers the absorbent in the solution heater to a tube side of the membrane distillation generator; after diffusing to the shell side through tube walls in the membrane distillation generator, the vapor in the absorbent enters into the condenser for condensation; the condensed vapor enters and absorbs heat in the evaporator after pressure reduction by the throttle valve, thus realizing cooling. The absorption type refrigeration device adopting the technology of membrane distillation can effectively reduce the temperature of the heat source, improve the utilized temperature difference of the hot water generated by the solar energy collector and in the generator, enlarge the scope of air emission of pair of working substances and reduce the cooling water consumption of the generator so as to further improve the performance coefficients of the system.
